Ah...now I see. Right above the "MOD4" section is parm10.dat, there are set
of equivalences:
N NA N2 N* NC NB NT NY
C* CA CB CC CD CK CM CN CQ CR CV CW CY CZ CP CS
This means that all of the shown nitrogen parameters are the same as "N",
and the listed carbon parameters are the same as "C*". So, for CA, look in
the MOD4 section for "C*".
....dac
